Check the fuel pressure regulator. take off the vac hose and if gas comes out of hose, the regulator is bad.

My toyota hiace with 2kd engine is producing a cloudy black smoke and hard stating what could be the problem


Black smoke means too much fuel .
Have you changed your air filter or is it clean. A dirty air filter will flood your engine.
Is your choke working properly?
Could be your carburetor float is sticking.
Not sure but there are computer sensors in some makes that could cause flooding if they are not working properly.
I am sure there are other things that could be the cause but you can start here.

I have a Brute Force 750, starts OK but runs rough after a few minutes, will start smoking a smelly black/gray smoke, and most recently some blue smoke.


When the head gasket fails on a liquid (water) cooled engine the typical smoke colour is white (steam) and that becomes rather underlined by the steady drop of the coolant level and often clear evidence combustion gas is leaking into the cooling system.

Smelly black/grey smoke tends to be produced by an over-fuelling condition such as a stuck choke or strangler or other cold starting aid or perhaps carburettor flooding.

Blue or blue/grey smoke is invariably engine oil burning but I suggest you ignore that until the black smoke problem is rectified and after a short time the blue smoke might also disappear. If it doesn't it could be related to the overheating but the black smoke probably wasn't caused by that...

What would black smoke at idle with brakes on indicate when in gear(automatic)


Black smoke is an indication of a too much gas, like a choke sticking on, in the old days. For some reason your computor is putting out the wrong reading when you put the car in gear. It's most likely a sensor going bad or a wire unplugged maybe. While it shouldn't do any damage to the car it will be very ******* the wallet. You should take it in and have it checked out. Hope this helps.

Ill turn on my car and it won't start unless my foot on the gas. It will turn on here and there. As soon as it turns on it throws black smoke and a terrible smell like gas mix with alcohol. I change the...


Hello,

Black smoke is usually a sign of the accelerator pump set wrong, a choke plate could be partially closed and it could also be a really clogged air filter. If you pulled the air filter and the car turned on with no problems then replace it as this is one of the reasons for black smoke. It's not often a gas vehicle blows black smoke. The vehicle is starving for air.

I have an old slant 6 carburetta engine and when i rev the motor it blows alot of grey smoke out the tail pipe


Sounds like the valve guides are worn. They will wear excessively due to the fact that
the gas currently sold has less lead content than what was sold when these motors
were manufactured. This also affects the rings as well. You could have the heads
rebuilt with new valve guides that are designed for the new fuel. The lead acted as a
lubricant. Also given the age of that engine, I would rebuild the carbeurator as well
if it exhibits black smoke, and replace the choke during rebuild. A sticking choke
will make it hard to start and plenty of black smoke. Hope this helps.

Have to push gas pedal to the floor for car to start. its an 89 gt mustang with the 5.0l. after it starts it runs fine, sometimes the engine light comes on when i get on it real hard. but there are no hard...


This would indicate a problem with the automatic choke. Putting the pedal to the floor creates the same effect as the choke when starting the car.

Flooding,black smoke,run hard,choke sticking


The first thing i would look at here is the choke pull. Make sure that after the car starts, the choke props open. Also, as the engine warms, make sure the electric choke is opening up. If not, make sure you have 12V to the choke. If so, replace it. This should solve the problem.

But let me know if you need any further assistance, ok? We'll get it working! :)

It's the automatic choke!

The choke is "closed" or barely open... When cold, the engine needs a RICH mixture (more gasoline, less air). When the engine warms up, it requires a LEAN mixture (less gas, more air).

It is probably creating BLACK tailpipe smoke ... that means unburnt gasoline. (Blue smoke is OIL, white smoke is WATER).

Put the parking / emergency brake ON.
1. Remove air cleaner assembly from intake, use a carb cleaner spray or throttle body spray cleaner and spray just a little. (AutoZone $5)
2. Find the accelerator2.gif arm under the hood.
3. start car, rev the engine to make sure how to operate the accelerator from under the hood.
4. Carefully spray into carb / throttle body and work the accelerator ... don't let the engine die...
5. Watch out for "backfire"... it may create a small flame out of the carb. It will extinguish itself in one second.

6. You may need to do this two, three times.
7. Add a "complete fuel system2.gif cleaner" to your next tank of gas ($8).

That's it! ... pretty cheap, too.

Hope this helps!
